I have had the exact same issue on Visible with 220.127.116.11 and FW A05. I am not sure what causes this to happen. I switched my LBR20s so the one refusing to connect to Visible connected to ATT without issues. The other LBR20 had been on ATT for months connected with the Visible sim with no issue. I just had to update the configurations a bit (just the APNs).outrage18 wrote: ↑Fri Mar 26, 2021 2:39 pmNever used the orbi app, but Netgear tells me that it will notify me of updated fw availability. SOO, I just installed the Android version and lo and behold, it is gave me an option to update to fw version 18.104.22.168; which is NOT available on the Netgear LBR20 download site... Since, I've little to lose, I upgraded. As expected, lbr worked fine after upgrade and survived 2 reboots.
I then tried the circle_jerk automated install script which failed with message "...No connection could be made because the target machine actively refused it at 192.168.1.1:23" However, manual install worked. I was able to enable circle, ssh in and make minimal necessary changes to call_once and fw_rules scripts. Speedtest.net showed excellent unthrottled speeds on Visible. I then rebooted and once again the LBR failed to connect. Statistics is showing "link Down" for WAN, LAN and LTE. Connection status shows 0.0.0.0 both for IP address and DNS Server; while SIM is READY and SIM IMSI is shown correctly. In addition, Band Number is shown as '2' which is a Visible/vzw band available here. But Connection Status is 'disconnected'
Update: Netgear is processing an RMA to replace my unit.
I haven't yet tried to switch back. I am wondering if something in the Visible SIM config is causing the issue.
What is the best way to factory reset the modem of the LBR20? Is the AT&F command the best way to restore the modem to factory defaults and delete carrier network configurations? I have not tried sending the modem this command to see if this might fix the issue, then re-insert the SIM as things are working now, but I suspect the same issue will eventually happen to all my LBR20s with Visible.
